Given concerns about the effects of climate change on precipitation regime, in the future, some mountainous areas may likely experience more landslides with a faster response to rainfall; however, most such projections are weakly based and remain untested [10,11]. Subsurface hydrology is usually the main triggering mechanism of these landslides and associated debris flows. While the effects of hillslope hydrology on runoff generation have been thoroughly studied, much less attention has been paid to these effects on landslide and debris flow initiation. Recent syntheses demonstrate that it is no longer appropriate to view the subsurface as a static media which facilitates the transit of subsurface water, rather a variety of factors affecting the dynamics of subsurface hydrology need to be considered [12,13].

Landslides, and Affected the Eruption Patterns of Some Geysers
Earthquake Annex I Colorado State Emergency Operations Plan LEAD AGENCY: Dept. of Local Affairs, Office of Emergency Management SUPPORTING AGENCIES: Governor's Office, Personnel & Administration, Corrections, Labor & Employment, Military Affairs, Natural Resources, Public Safety, Transportation, Education, Human Services, Red Cross, Salvation Army, COVOAD I. PURPOSE This annex has been prepared to ensure a coordinated response by state agencies to requests from local jurisdictions to reduce potential loss of life and to ensure we maintain or quickly restore essential services following an earthquake. It is designed to supplement the operational strategy outlined in the Basic Plan. II. SITUATION The Southern and Middle Rocky Mountains extend from the mountainous parts of central and western Wyoming and northeastern Utah, through the rugged mountains of central Colorado, southward into extreme north-central New Mexico. Large, damaging earthquakes in this region are uncommon, but significant historical earthquakes have caused damage. The largest earthquake in the Southern and Middle Rocky Mountains occurred on November 8, 1882, and, although poorly located, probably was in north-central Colorado, west of Fort Collins and northwest of Denver. The earthquake occurred before the development of seismometers, but it had an estimated magnitude of 6.6 and was felt throughout most of Colorado and in adjacent parts of Wyoming, Utah, Idaho, and Nebraska. The most seismically active part of the Southern and Middle Rocky Mountains is in northwestern Wyoming near Yellowstone National Park, where ongoing volcanic activity is responsible for the spectacular geysers and other unique geologic features in the park. On June 30, 1975, a magnitude 6.4 earthquake shook the park, caused rockfalls and landslides, and affected the eruption patterns of some geysers.

Home owners should consult an erosion control professional for assistance with more difficult circumstances. After the Fire The effects of fire can be felt long after the flames are extinguished. Rates of erosion and runoff can increase to unsafe levels when trees, shrubs, grasses and other groundcover are no longer present. Under normal circumstances, roots help to stabilize soil, while stems and leaves slow water down, giving it time to absorb or soak into the soil. These protective functions can be severely compromised or even eliminated by fires. In the aftermath of a fire, the potential for flooding, debris flows, and erosion is greatly increased. Fortunately there are many things you can do to protect your home or business from the damaging effects of a fire: Flooding - Flooding may occur even during moderate storms as rain falls on areas where vegetation has been destroyed by fire.

U.S. DEPARTMENT OF THE INTERIOR TO ACCOMPANY MAP MF-2329 U.S. GEOLOGICAL SURVEY MAP SHOWING INVENTORY AND REGIONAL SUSCEPTIBILITY FOR HOLOCENE DEBRIS FLOWS AND RELATED FAST-MOVING LANDSLIDES IN THE CONTERMINOUS UNITED STATES By Earl E. Brabb, Joseph P. Colgan, and Timothy C. Best INTRODUCTION Debris flows, debris avalanches, mud flows, and lahars are fast-moving landslides that occur in a wide variety of environments throughout the world. They are particularly dangerous to life and property because they move quickly, destroy objects in their paths, and can strike with little warning. U.S. Geological Survey scientists are assessing debris-flow hazards and developing real-time techniques for monitoring hazardous areas so that road closures, evacuations, or corrective actions can be taken (Highland and others, 1997). According to the classifications of Varnes (1978) and Cruden and Varnes (1996), a debris flow is a type of slope movement that contains a significant proportion of particles larger than 2 mm and that resembles a viscous fluid. Debris avalanches are extremely rapid, tend to be large, and often occur on open slopes rather than down channels. A lahar is a debris flow from a volcano. A mudflow is a flowing mass of predominantly fine-grained material that possesses a high degree of fluidity (Jackson, 1997). In the interest of brevity, the term "debris flow" will be used in this report for all of the rapid slope movements described above. WHAT CAUSES DEBRIS FLOWS? Debris flows in the Appalachian Mountains are often triggered by hurricanes, which dump large amounts of rain on the ground in a short period of time, such as the November 1977 storm in North Carolina (Neary and Swift, 1987) and Hurricane Camille in Virginia (Williams and Guy, 1973).
